BARREL CLOSURE.

i Application led January 21, 1927. Serial No. 162,647.V

This invention` relates to a closure dei signed more particularly for steell barrels, such as are used, for example, forshipping chemicals in bulk. Inloading and unloading such containers, they are subjected to severe shocks and. rough usage liable to loosen and release their covers. y

One object of theinvention is the provii sion of a simple and positive lock which will reliably retain the barrel cover in place under all conditions of use and at the same time permit, its quick and convenient release for emptying the barrel. l i

Another object is tov so construct the bau rel as to prevent pocketing of any of its content-s in emptying it.

In the accompanying drawings Figure lis a vertical` section of the upper part of a barrel embodying the improvement. Figure 2 is a similar section of a fragment of the barrelwith the locking de vice removed. kFigure 3 1s a section similar to Fig. 1, showing a modified form of the barrel. Figure 4 is a fragmentary vertical section of the barrel showing another modifi` cation.

Similar characters of Vreference indicate corresponding parts throughout the several views.

Referring to the preferred embodiment of the invention, illustrated in Figs. 1 and 2, l() indicates the body of the barrel having a wide or deep internal bead 11 Vnear its upper end, and 12 is a head or head-ring secured in the end of the body by interlock-` ing flanges 13, 14 or other suitable means. This head has a relatively large central opening bounded by a depending neck 15 in which the removable cover 16 is tted. This neck bears against the vertical portion of E the bead 11 and its lower edge is bent outwardly to form a li or flange l5 which bears against the bea forming a tight joint at this point which prevents any of the contents of they barrel from entering between said bead and the cover-neck. The cover 16 is cupped or dished and has a closed bottom.

At its upper end, it is provided with an out-` wardly-extending stop-flange 17 between gasket 18 may be interposed. The wall of the cover extends below the neck 15 and is provided below and adjacent to its lower edge with unthreaded transverse openings 19 arranged at suitable intervals around its circumference. Through these openings pass which and the face of the head a packing locking members which extend outwardly under the lower` edge of the neck 15 so as to reliably retain the cover in place inthe barrel-head. In their preferredform, these locking members consist of` tapering screws 20 having sharp threads,` asshown, which cut into the walls of the smooth openings when the screws are driven home, thereby positively holding them from-longitudinal displacement in the openings. To afford a more extensive bearing for thescrews,

smooth-bored' collars. 21 preferably extend from the outer vedges of said openings, the screws cutting their own threads into these collars as well as the walls of the openings.

The threads of the screws preferably extend to their heads, so that the latterl are clampedy against the inner side of thecoveiwall upon tightening them, holding them more secure ly 1n place.

To remove the cover, it is only necessary to unscrew the screws tar enough to clear the lower edge of the neck 15. This forms-an exceedingly simple and inexpensive lock which is positive and reliable and yet permits ready unlocking of the cover.

The bead 11 fills and closes the space ben tween the wall of the barrel and the neck of the barrel-head, avoidingthe formation of a trap or pocket under the head which is liable to catch material in emptying the barrel. To facilitate the discharge of the contents, the lower side of the bead llmay be inclined, as shown at 22 in Fig. 4,..

The construction shown in Figs. 1 and 2 is designed for barrels having comparatively large covers.

Figure 3 shows aY modified construction embodying the improvement and kintended for containers with a smaller cover. In this case, the head-ring of the barrel is wider than that of the first-described construction` and thebody-bead 11 is omitted.

I claim as my invention n 1. A barrel having a head provided with an opening bounded by a depending neck, the wall of the barrel being provided adjacent to said head with an internal bead extending from said wall to said depending neck to fill the space between said parts and prevent pocketing ofthe contents under the head. l

2. A barrel having a head provided with an opening bounded by a depending neck, the wall of the barrel being provided adjacent to said. head with an internalybeed extending from sind well to sind depending neck, said neck having at its lowerv end an outwardly-extending li J which bears against the underside of said cad.

3. A barrel having n head provided with an opening bounded by a depending neck,

the wall of the barre-l being provided adjecent to said head with an internal bead extending from said wall to said depending neck, said neck having nl' its lower end an outwardly extending lip which beure againfai t-he underside oi Sfiid bead, n diehed removable, cover fitting in said neck und having in itf; upright wall an opening located adjacent lo the lower edge oi the neck, and a loelescrew for said cover passing through Said opening, engaging under Said neck and having its thread interlocked with the opening.4

4. The combination with a barrchhead having an opening bounded by a depending neck, areinovable cover having an upright wall fitted in said .neck and extending below it, said wall having an opening located below and adjacent to the lower edge of the neck, and a removable locking member for the cover passing through said opening and engaging nnder seid neck, said locking ineinber having ineens interlocking with seid opening to positively hold it from longitu dinal displacement therein.

5. The combination with a barrel-head having an opening'` bounded by n depending neck, a removable cover having an upright wall litted in .said neck and provided :it ilu` upper end with a projecting llange, said cover-wall extending below Suid neck und havingr an opening locntcd below and adjacent to the lower edge thereof, and :xA lock- Icrew passing through saidopening and having Sharp threads `which cnt into the edge ol the opening when the screw is: driven honic.`

(j. The con'ibinntion with a bari'cl-lnnld hnvingl an opening bounded h v :i depending neck, a removable cover having nn upright wall fitted in said neck and provided at its upper end with a projecting flange Said covcrwall extending below said nec; :ind having an opening located below and iuljn cent lo the lower edge thereof' and :L collar Amending from the outer edge of seid opening, said opening and collar being nnthrezlded. and a lmflzf--crcw panning through said opening and said collar and having sharp ihreadeY which cut into the wolle thereof when i'hc screw driven home.
